Add a misctrl specific message with its first use.
Future platform flags can go here for any purpose,
without needing to add separate utilities.
Check if a device has ever been in 16KB before so that
we are able to tell if 16KB causes any issues.

misc partition operations for the Android platform, rather than
having to write a new tool each time.
